[android-developers] Re: Adapter fetches and parses RSS feed to get data - best practice?

Many an atrocity has been committed in the name of "best practices",
"object oriented design", "design patterns", et al. (Not to mention
"performance".) Any time someone's throwing around buzzwords like
that I tend to run the other direction.

Ultimately, the only criteria for good code is that it works, it does
the required job in a timely fashion, without excessive use of
resources, it's reliable, it's maintainable, and it was written with a
reasonable amount of effort and expenditure. Any code that
accomplishes those goals is good code. Any that doesn't isn't, no
matter how high-falutin' the technology is.
